NAME

       nilfs_cleanerd - NILFS2 garbage collector

SYNOPSIS

       nilfs_cleanerd [-hV]

       nilfs_cleanerd [options] device [directory]

DESCRIPTION

       nilfs_cleanerd  is a system daemon which reclaims disk space of a NILFS2 file system found
       in device.

       The optional directory argument specifies the mount point where the daemon  operates.   It
       must be an r/w-mount.

       This  program  can  be  invoked  either automatically by mount.nilfs2(8) or manually by an
       administrator.   However,  users  are  recommended  to   invoke   nilfs_cleanerd   through
       mount.nilfs2(8) or mount(8) and shutdown it through umount.nilfs2(8) or umount(8) in order
       to avoid state inconsistencies among administration tools.

       nilfs_cleanerd displays its process ID (pid) to standard output when it started.

OPTIONS

       -V, --version
              Display version and exit.

       -h, --help
              Display help message and exit.

       -c file, --conf=file
              Specify configuration file.

       -p interval, --protection-period=interval
              Override protection period with the specified number of seconds.

SIGNALS

       nilfs_cleanerd reacts to a set of signals.  You may send a signal to nilfs_cleanerd  using
       the PID shown by the mount command (or in /etc/mtab):

              # mount -t nilfs2
              /dev/sdb1 on /nilfs type nilfs2 (rw,gcpid=PID)
              # kill -SIGNAL PID

       SIGHUP This  lets  nilfs_cleanerd  perform  a  re-initialization.   The configuration file
              (default is /etc/nilfs_cleanerd.conf) will be reread.

       SIGTERM
              The nilfs_cleanerd will exit cleanly.

       SIGUSR1, SIGUSR2
              Reserved for future use.  These let nilfs_cleanerd die at present.

FILES

       /etc/nilfs_cleanerd.conf
              Configuration file for nilfs_cleanerd.  See nilfs_cleanerd.conf(5) for details.
